I want to use the "LogiCORE IP AXI IIC Bus Interface" for interfacing some I2C-devices (DDS, etc.).
I did have a look into the AC701-design which uses a "PCA9548ARGER" for multiplexing the I2C to different devices from the FPGA.
Is this really "necessary" or would it be sufficient to use an I2C-transceiver device which "convertes" resp. "conditions" the FPGA-signals to the I2C-side and which allows to drive the different I2C-devices?
For me it is not clear, what would be the benefit of using the "PCA9548ARGER" instead of e.g.: an JLC1563 (I2C buffer)?
